E. CARTER WINDOW FASTENER Aug. 23, 1938.

Filed Feb. 28, 1938 Patented Aug. 23, 1938 UNITED STATES PATENT orrlce 1 Claim.

This invention relates to a fastening device for securing a removable member, such as a storm window, screen, shutter or the like, toa fixed member, such as a window casing, frame or the 5 like, and its principal object is to provide an improved device which is of simple design and of strong and durable construction, which is efficient and reliable, and which may be manufactured and sold at a relatively low cost.

Further objects and advantages will be apparent from a consideration of the following description and the accompanying drawing, wherein:

Fig. 1 is a rear elevation of a portion of a window casing and a storm window secured thereto by means of a fastening device constructed in accordance with the present invention;

Fig. 2 is a vertical section through the assemblage shown in Fig. 1;

Fig. 3 is a front elevation of a portion of a window casing and a screen secured thereto by means of a fastening device constructed in accordance with the present invention;

Fig. 4 is an end elevation of the assemblage shown inv Fig. 3; and

Figs. 5 and 6 are perspective views of the different parts of the fastening device.

Referring to Figs. 1 and 2, the embodiment shown therein comprises a window casing provided with the usual sill II, and a storm window l2 which fits snugly against the casing I0, as shown more clearly in Fig. 2. The storm window is detachably secured to the window casing by means of a fastening device consisting of interlocking parts 15 and 16, shown in Figs. and 6.

The member l5 comprises a plate-like element 20 integral with a socket member 2| which is generally wedge-shape in longitudinal section. The plate-like element is formed with a pair of spaced openings 23 to accommodate screws or like fastening elements by means of which the member I5 may be secured to the frame of the storm window l2, and the rear edges of the socket 2| are provided with transversely aligned slots or openings 24 spaced from its lower end.

The member I6 comprises a plate-like element 25 integral with an offset, generally wedge-shaped head 26 of substantially the same size and shape 1 ings 24 formed in the rear edge of the socket member when the parts are in interlocking posi-. tion.

The members 5 and I6 are secured to the frame of the storm window and casing, respectively, at corresponding locations, as shown in Figs. 1 and 2, so that when the storm window is applied to the window casing these members are effective to hold the frame of the storm window snugly against the casing with the lower part of the latter contiguous to the sill. The socket and head elements 2| and 26 are so positioned that the weight of the storm window is effective to cause these elements to draw it inwardly, thus ensuring a snug fit and eliminating looseness between the parts, which might otherwise develop. If desired, the lower edge of the storm window may be provided with a weather strip 30 (Fig. 2). In orderto lock the fastening members I5 and I6, a small pin 32 (Fig. 2) may be inserted in the openings 24, 28, this pin, when thus positioned, being effective to prevent relative movement of these parts.

The embodiment shown in Figs. 3 and 4 illustrates the use of my improved fastening device to secure a screen to the window casing. In this embodiment the members l5 are secured to the vertical edges of the screen 35 and the members l6 are secured to corresponding locations on the outer face of the window casing |D.

In each of the embodiments herein shown four sets of fastening devices are used, although it is to be understood that if desired a greater or lesser number may be employed. In any case the storm window or screen may be readily attached to the window casing merely by applying it sothat the socket members I5 carried thereby fit over the heads 26, after which the locking pins 32 may be inserted into the openings 24, 28 to lock the parts in position. In order to remove the storm window or screen, it is merely necessary first to remove the locking pins and then lift the window or screen upward to disengage the members I5 and I6.

While I have shown and described one desirable embodiment of the invention, it is to be understood that this disclosure is for the purpose of illustration and that various changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be made without departing from the spirit and scope of the invention as set forth in the appended claim.

I claim:

A fastening device for securing separable members in fixed position, comprising a plate member formed with an integral oifset substantially Wedge-shaped head, said plate member being adapted to be secured to one of said members so as to hold said head in spaced relation thereto, said head having an opening in one face, a socket member adapted to be secured to the other of said members, said socket member having an opening in one edge thereof, the interior of said socket member being shaped to receive said head so that when in assembled relation the opening in said head registers with the opening in said socket member, and a locking member comprising a pin adapted to be inserted into the openings in said socket member and head so as to hold the parts in fixed position.

ERNEST CARTER.
